INTERMITTENT-TRANSMISSION MECHANISM.

Specification of Letters Patent.

Application led April 18, 1913. Serial No. 761,904.

To all wlw/m t may concern Be it known that I, CESARE CAMPUS, a subjectof the King of Italy, and a residentI of the city of'New York, boroughof Manhattan, in the county and State of N ew York, have made new anduseful Improvements in intermittent-Transmission Mechanisms, of whichthe following is a full, clear, and exact description.

This invention relates to new and useful improvements in. mechanicalmovements, the advantages following the use of a structure embodying theinventive idea appearing more fully as the description of theconstruction and operation thereof proceeds.

In the accompanying sheets of drawings,

wherein like reference characters refer to like parts in the severalviews- Figure 1 is a partial vertical sectional view of the refinedembodiment of the inventive idea; Fig. 1a is a similar view showing adifferent relation of some of the parts; Fig. 2 is a sectional view onthe line 2-2 of Fig. 1; Fig. 3 is a side view; Fig. 4 is a sectionalview of a modified form of some of the elements; Fig. V5 is a partialend view thereof; while Fig. 6 is a sectional View on the line 6 6 ofFig. 4.

A revoluble member, such as a wheel 1 is mounted on a shaft 2 to turntherewith, the shaft being mounted in bearings 3, which, in thisinstance. are carried by the easing 4 which serves to inclose the parts;the peripheral portion of the wheel is provided with a succession ofsubstantially similar and equally spaced pockets 5. Fixed on the shaft 2is a wheel 6 having the periphery thereof provided with a number ofserrations or teeth 7, equal in number to the pockets 5 on the wheel 1;a pawl 8. movably mounted on a pin or equivalent element 9. is adaptedto engage with any tooth 7 and thereby prevent turning of the shaft andthe wheels thereon in a counter-clockwise direction (Fig. 3); in orderto maintain the pawl in coiperative relation with any tooth a spring 10is employed, one end of which engages the outer end of the pawl and theother end of which engages a fixed support 11.

The wheel 1 is designed to partake of a periodic clockwise (Fig. 1)movement through the medium of parts to be now described. Areciprocating member 12 in the nature of a piston is mounted in thesupports 13 and is provided rwith a pin 14 whereby a pitman may beengaged therewith in order to impart movement thereto;

an opening 15 extends vtransversely of the member 12 and slidablymounted therein an element 16 having the upper end 17 formed to closelyengage in a pocket of the wheel 1 when the parts are in the positionshown 1n Fig. 1; the sides of this element are arched vas at 18 and theinterior thereof forms a container for a spring V19, onev end of whichbears against the bottom wall of the container; extending transverselyof this element 16 and through the arched sides thereof is a bar 20 theends of which are received in pockets 21 formed in the member 12; thelower end of the before-mentioned spring 19 bears against this bar theresult being that the end of the element 16 1s brought into position inone of the pook ets 5; the lower open end of the element 16 mav beclosed. if so desired. by a block 16e.

Fixed beneath the reciprocating member 12 is a seat 22 the upper face ofwhich inclines as shown particularly in Fig. 1. the lower end of theelement 16 being similarly shaped whereby it may rest thereagainst. lnthe position of the parts shown in Fig. 1 the reciprocating member 12 isat the end of its travel toward the right: rotation of the wheel 1 in aclockwise direction is prevented bv engagement of the pawl 8 with theserrated wheel 6. and rotation of the wheel 1 1nV a counter-clockwisedirection is prevented bv reason of the engagement of the element 16with a pocket of the wheel and the seat 22: the wheel is thus locked inposition: it is to be particularlv noted from Fig. 1 that the top andbottom side.c of the element 16 are parallel. these sides being Valsoparallel with the top face of the seat 22 and the wall of thepocret 5 inthe wheel 1: the upper end 17 of the element 1.6 and the pocket 5 are ofsuch extent that large bearing s urfaces are provided.

As the reciprocating memberV 12 moves toward the left of Fig. 1 theelement 16 is forced downwardly because of the inclination of the wallof the pocket 5. further movement of the said member bringing they upperend of the element 16 into position in the next pocket 5. as shown inFig. 1a, the spring 19 urging the element into engagement as described:on the return movement of the reciprocating member toward the right ofthis figure the wheel 1 is moved the distance of one tooth, the wheelturning rel- Patented Mar. 16, 1915.V

atively to the end 17, the rounded conforma-Y tions of the upper end ofthe element 16 and the pocket 5 permitting relative turning of theseparts. The parts are designed to operate submerged in oil, the casingbeing` formed to contain a suitable amount thereof; if so desired themember 12 may be provided with a number of channels to receive oil forlubrication` a pocket 2% being provided eX- teriorly of the casing toreceive any overflow, an outlet being formed in the pocket in order towithdraw it therefrom; an outlet 1.00 is also provided for oilcirculation.

Various devices may be used to maintain the element 1G in engagementwith one of the pockets 5 and in Figs. l to 6 inclusive a modifiedconstruction is set forth; the element 1G is mounted in an opening 15 inthe reciprocating member 1Q as already described, the element beingprovided with a recess 26 and the side wall thereof with an opening 27communicating with the recess; the rear end of the reciprocating member12 is provided with a recess 28 in which a lever 29 is positioned, beingmounted on a shaft 30 extending transversely of the recess; one of thearms 30 of theflever extends through the opening- 27 into the recess 26in the element 16 and is provided with a pocket 31 in which one end of apost 32 is received, the other end of the post being engaged in pocket33 formed in the wall of the recess 26 in the element 16; thearrangement of the post and the pockets provides, in effect, a universalconnection.

Fixed to the end of the support 18 is a bearing Sil having a sleeve 35therein, the inner end of which is provided with a flange 36, a key-way37 extending longitudinally of the sleeve; the outer' end of this sleeveis threaded and receives a plug 38 having a. squared end 3S on which anarm 39 is carried, the arm being provided with a counterpoise a0;positioned on the outside of this sleeve is a collar 41, a pin l2passing through the plug; sleeve and collar and maintaining the parts infixed relation; the collar l1 and the flange 36 prevent movement of thesleeve 35 longitudinally of the bearing 34.

Fixed in the outer open end of the recess 28 in the member is a bearing-L13 held in position by means of the pins ll, the bearing supporting ashaft 45; the position ofthe shaft within the bearing is insured bymeans of the flanges 116, L17 carried thereby; the inner end of thisshaft is provided with an arm d8 which engages with the arm 4:9 of thelever 29 and which tends to turn the lever about the support 30 therebyurging the element 16a upwardly; the outer end of the shaft ll5 extendsinto the sleeve 35 and is provided with a key 50 which engages in thesaid key-way in the sleeve.

The arm 39 and counterpoise Ll() donot hang vertically but aremaintained at a suitable angle to a vertical plane passing through thecenter of the sleeve 35 so that there is a constant tendency of thissleeve to turn; by reason of the engagement of the lrey 50 and key-way37 the shaft l5 also tends to turn in the same direction, whichdirection is such that the arm 49 of the lever 29 is moved downwardlyand the arm 30a of the same lever upwardly, the resultv being that theelement 16a is moved upwardly and brought into engagement with oue ofthe pockets 5 in the wheel 1 during operation of the machine the member1Q and the shaft l5 move back and forth, the shaft being always inengagement with the sleeve 35 by reason of the lrey and hey-waydescribed, the result being that the element 16 is constantly influencedby a force urging it upwardly; the value of this force may, of course.be varied. by changing the angle between the vertical plane and theplane passing` through the arm 39 and the counter-poise 40.

The movement described is adapted to a variety of uses; the particularrelation of the parts insures the locking of the wheel 1 at determinedtimes which is advantageous in different forms of machines performingdifferent operations.
